Did you set editable=true on the DG? If so, it should update the data on itemEditEnd and not on change.

Hello. I have a DataGrid with a column of ComboBoxes. The behavior I'm seeing is this: 1) I click on a ComboBox - it expands 2) I choose a value - it collapses 3) I click on a ComboBox in a different column 4) It expands - then immediately collapses I have determined why it is happening, but I'm not sure how to make it stop. I have a separate mxml file where I define the ComboBox and I override the set data() method. The set data() method sets the value in the ComboBox in each row. The issues is that after I change a ComboBox in one row, set data() is called on all rows - so as soon as I click on the second ComboBox, set data() is called (because I clicked away from the first ComboBox), the value is set in the second ComboBox - and it collapses. So, if I change the value in one ComboBox, click to some other cell, then click on the second ComboBox, it works fine (because set data() is called when i click to the other cell). So my questions is, how do I make this work? Can I force the call to set data() as soon as the first ComboBox collapses (my putting focus on another component temporarily?)? Or can I make it bypass the set data() call from ComboBoxes which weren't touched? Any help is greatly appreciated. Code is below, if it helps...
